Problems solved by technology

The composition of industrial sewage is complex, especially a large number of artificially synthesized compounds entering the environment. These substances are mainly industrial COD, ammonia nitrogen, sulfide, etc., which enter the environment with the wastewater or solid waste discharged from the factory. The unfamiliarity of these pollutants cannot be decomposed and utilized by microorganisms in a short period of time. The traditional wastewater treatment method using activated sludge to cultivate and domesticate microorganisms can no longer effectively remove these pollutants. These substances have accumulated in the environment for a long time and provide us with The living ecological environment has caused great pollution, which has brought great harm to human physical and mental health.

Embodiment 1

[0027] A method utilizing biochemical technology to treat environmental geology industrial wastewater, comprising the steps of:

[0028] Step 1) preparation of compound bacterial agent, step 2) preparation of compound algae liquid, step 3) preparation of microbial carrier, step 4) preparation of microbial preparation; step 5) biochemical technology treatment.

[0029] Specifically, include the following steps:

[0030] Step 1) Prepare compound bacterial agent:

[0031] Put the peanut shell and straw into the pulverizer according to the weight ratio of 1:1, and pass through a 100-mesh sieve after crushing to obtain a composite powder; respectively cultivate Bacillus megaterium, Acinetobacter baumannii and Sphingomonas to concentration 1×10 7 cells / ml of bacterial liquid, and then mixed according to the volume ratio of 2:1:1 to obtain the mixed bacterial liquid; the mixed bacterial liquid and the composite powder were mixed evenly according to the weight ratio of 1:1 to obtain...

Embodiment 3

[0060] Effect test of treatment of environmental geological industrial wastewater:

[0061] Water sample selection: Take the industrial wastewater of a sewage treatment plant as an example;

[0062] Test group: according to the method of Example 2 of the present invention.

[0063] Control group 1: Diatomaceous earth was used as the microbial carrier; the microbial compatibility was the same as that in Example 2; treatment method: after three days of continuous dosing, 5g / m3 per day, and then left to stand for six days, the detection and treatment results are shown in Table 1.

[0064] Control group 2: The microbial carrier is the same as in Example 2, the difference is that only three kinds of bacteria are added, but no algae is added; treatment method: add 5g / cubic meter on the first day, and then let it stand for six days to detect the treatment results See Table 1.

[0065] Table 1

[0066] Before treatment (mg / L) After treatment (control group 1) (mg / L) ...

Description

technical field [0001] The invention belongs to the field of environmental geological industrial wastewater treatment, and in particular relates to a method for treating environmental geological industrial wastewater by utilizing biochemical technology. Background technique [0002] Environmental geology is a collection of geology, geological issues and related change information that affect human survival and development environment. The emergence and use of environmental geology in our country is relatively late, and it was also proposed as a series of serious environmental problems (such as environmental pollution, geological disasters, etc.) have more and more prominent impacts on production and life. Environmental geological wastewater mainly includes industrial wastewater, biological wastewater and agricultural wastewater. Industrial wastewater refers to the wastewater generated in the process of industrial production, which contains industrial production materials, i...
